[0007]

According to the present invention, the expiration date information read from the storage means by the control means provided on the card is compared with the current time information by the time measurement means, and the two information have a predetermined relationship. Inform the user accordingly.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a block diagram of a first embodiment of a card and a card-type traffic monitoring system using the card according to the present invention. This system is an embodiment of a so-called wireless card system in which communication between a card and a traffic monitoring unit is performed wirelessly.

First, the configuration of the card will be described. The card includes an antenna 1, a radio unit 2 for transmitting and receiving radio waves via the antenna 1, and a ROM for storing expiration date information and the like.
(For example, EEPROM; Electrically
Erasable Programmable RO
M) 3, a clock unit 4 for outputting current timekeeping information, a notification unit 5, a power supply (battery) 6, a radio unit 2, a ROM 3,
It comprises a clock unit 4 and a control unit 7 for controlling the notification unit 5.

Next, the configuration of the control unit will be described. FIG. 2 is a configuration diagram of the control unit. The control unit 7 includes a communication operation identification unit 11 for identifying whether the wireless unit 2 is communicating and a clock unit 4.
Date reading unit 1 that reads the current date output from
2, a fixed time elapsed identifying unit (timer unit) 13 for identifying the elapse of a fixed time, and a notification driving unit 1 for driving the notification unit 5
And a control unit 15 for controlling the communication operation identifying unit 11, the date reading unit 12, the constant time elapse identifying unit 13, and the notification driving unit 14.

Next, the configuration of the monitoring device will be described.
In FIG. 1, a monitoring device 20 is a known device, and includes a transmitting / receiving device (not shown) and a CPU (central processing unit) (not shown) for decoding information such as expiration date from the card. Antenna 21 for performing the two-way communication.

Next, the operation of the card-type traffic monitoring system will be described with reference to flowcharts. FIG. 3 is a flowchart showing the operation of the first embodiment of the card-type traffic monitoring system. First, the monitoring device 2 via the antenna 21
The signal transmitted from 0 is received by the wireless unit 2 by the card via the antenna 1, converted into a readable signal, and sent to the control unit 15. Then, the control unit 15 sends data to the monitoring device 20.

Next, the control unit 15 determines whether communication is in progress via the communication operation identification unit 11 (step 201).
If it is not communicating, it waits. If it is communicating, it proceeds to step 202.

Now, a signal from the monitoring device 20 is transmitted to the radio unit 2
, The control unit 15 determines that communication is in progress via the communication operation identification unit 11, and reads out data such as the expiration date stored in the ROM 3 (step 202).
Next, the current date is read from the clock unit 4 via the date reading unit 12 (step 203), and it is determined whether the current date and the expiration date have a predetermined relationship (step 204).

Here, the predetermined relationship is a case where the result obtained by subtracting the current date from the expiration date becomes, for example, "3 days". That is, it is determined whether the expiration date is within "3 days". Of course, the date is not limited to three days, and can be arbitrarily set as long as the date is a positive value.

If the result of the determination is within three days, the control unit 15 drives the notification drive unit 14 to cause the notification unit 5 to perform a notification operation such as sounding (step 205). This sound allows the user to know that the expiration date of the card is approaching.

If the result of the determination is 4 days or more,
The control unit 15 returns to step 201 again and thereafter repeats the same operation.

In the present embodiment, comparison with date data such as the expiration date is performed, but this can also be performed using time data such as usage time. Further, it is also possible to store data such as use start information and make a judgment based on a time relationship from the use start time.

The notification operation according to the present embodiment is performed by sounding. However, the notification operation may be performed by light emission by an LED (light emitting diode), vibration by a vibrator, display by a display, or the like.

Next, a second embodiment will be described. FIG.
Is a flowchart showing the operation of the second embodiment. Second
The operation of the embodiment is the same as that of the first embodiment up to step 204, and is different therefrom.

The controller 15 determines whether the current date and the expiration date have a predetermined relationship (step 20).
4) When a predetermined relationship is established, a certain time elapsed identifying unit 1
3 is driven, and it is checked whether or not a certain time has elapsed from the certain time elapse identifying unit 13 (step 210). Then, when a signal indicating that a certain time has elapsed is received, a notification operation such as a sound is performed (step 205).

This is a convenient function when it is not desired to immediately perform the notification operation. In other words, if a predetermined time, for example, “30 minutes” is set in the predetermined time elapse identification unit 13, the notification operation by a sound or the like is performed 30 minutes after the user passes through the gate or the like. Can be.

Next, a third embodiment will be described. FIG.
FIG. 9 is a configuration diagram of a third embodiment. In the third embodiment, a light receiving unit 21 and a light emitting unit 2 are used instead of the antenna 1 in the first embodiment.
2, the receiving unit 23 and the transmitting unit 2 are provided instead of the wireless unit 2.
A data converter 2 for converting transmission / reception data (serial data) into parallel data and sending it to the controller 7
5 is provided. Other ROM 3, clock 4,
The notification unit 5, the power supply 6, and the control unit 7 are the same as in the first embodiment, and the operation is also the same as in the first and second embodiments.

In this embodiment, communication with the monitoring device 20
For example, infrared rays can be used.

Finally, a fourth embodiment will be described. FIG. 6 is a configuration diagram of the fourth embodiment. In the fourth embodiment, communication between the card and the monitoring device 20 is performed by wire.

In the fourth embodiment, a wired transmission / reception unit 31 is provided in place of the antenna 1 and the radio unit 2 of the first embodiment,
An input / output unit (not shown) serving as an insertion port into a slot is formed at the end of the transmission / reception unit 31. (That is, an insertion slot to the slot is formed at the end of the card.) The other ROM 3, clock unit 4, notification unit 5, power supply 6, and control unit 7 are the same as those of the first embodiment, and the operation is the first. Second
This is the same as in the third embodiment.

On the other hand, an input / output unit (not shown) of the monitoring device 20
Is connected to one end of a signal line 32 instead of the antenna 21,
The other end is connected to a connection terminal (not shown) of the slot 33.

The user inserts the insertion slot at the end of the card into the slot when passing through a gate or the like. Thus, the control unit 7 performs the same operation as described above.

[0029]

According to the present invention, the storage means for storing at least the expiration date information on the card, the timing means, the notifying means for performing the notification, the expiration date information read from the storage means, and the time measurement The current time information measured by the means is provided with a predetermined relationship, for example, a control means for driving the notification means when the expiration date is approaching, so that even if the user forgets to see the display of the expiration date, Expiration can be recognized in advance.

Further, since all of the functions for monitoring the expiration date information are provided on the card side, the present invention can be realized only by changing the card side without changing the existing monitoring device.
